DEUT773 If one avert his eyes from charity, it is as if he serves idols (Kesubos 68a), and he is called "wanton," "wicked," "cruel," and "sinful." "Wanton," as it is written [this verse]. "Cruel," as it is written (Mishlei 12:10): "And the mercies of the wicked are cruel." And he thereby denies his ancestry, seeming not of the seed of Avraham, Yitzchak, and Yaakov, who are all merciful, but rather of that of the nations, who are cruel, (Yirmeyahu 50:42): "They are cruel and have no pity." And all who show mercy are granted mercy by Heaven, as it is written (Devarim 13:18): "And He will give you mercy and have mercy upon you and multiply you" (Shabbos 151b).
